Unable to stop automatic reconnection attempts

[solofx]

I've got some code that establishes a connection to my socket.IO server, which works perfectly well and allows messages to transit back and forth. The connection is established with auto-reconnection enabled for fault tolerance.

void connectToSocket() {
  IO.Socket socket = IO.io(socketUrl,
    IO.OptionBuilder()
      .setTransports(['websocket'])
      .enableAutoConnect()
      .enableReconnection()
      .build()
  );

}

I have functionality within my application for the user to change the connection URL to switch servers. When this happens, I need to disconnect the existing connection, prevent any re-connection attempts and establish a replacement connection.

I've tried calling various methods to terminate the existing connection, however the reconnection attempts persist in the background, even once the replacement connection has been established. For example:

socket.disconnect();
socket.close();
socket.clearListeners();

connectToSocket();

So far the only way to effectively stop the connection attempts is to terminate the application, which seems a little extreme. Am I missing something or is this expected functionality? If so, does an approach exist to stop an automatically reconnecting socket instance?

My version of the socket.io client is "2.0.3"
